Invoice9

Invoice9 is a Shopify app in the Invoices and receipts category. Invoice9 automatically generates EU-compliant invoices for every Shopify order. It detects the buyer's country, selects the correct format (ZUGFeRD for Germany, Factur-X for France, PEPPOL for Belgium and Netherlands), validates EU VAT numbers via VIES, and sends the invoice by email — with no manual steps. Issue credit notes in one click, sync invoices to Google Drive, and support customers in their language with built-in multi-language invoice delivery.

Invoice9 offers a free plan and 2 paid plans starting at $10/month and going up to $25/month. The free plan includes 50 invoices/month, ZUGFeRD, XRechnung, Factur-X, PEPPOL, VIES VAT validation, and PDF email delivery. The paid plans unlock advanced features beyond what's available on the free tier.

Invoice9 does not currently carry Shopify's Built for Shopify badge. The badge is awarded to apps that meet Shopify's published standards for performance, ease of use, and merchant value — many high-quality apps operate without it.

Merchants commonly compare Invoice9 with Order Printer Pro, Vify Order Printer PDF Invoice, EZLabel, and Order Printer Templates. Each alternative covers a similar use case but differs on pricing model, integration depth, and the specific themes merchants praise in reviews — see the alternatives section above for a side-by-side.
